I. R. SHANK, OF BUFFALO, VIRGINIA.

LATH-MACHINE.

Speccaton of Letters Patent No. 9,804, dated J' une 21, 1853.

To all whom t may concern Be it knoWn that I, I. R. SHANK, of Buffalo, Putnam county, and State of Virginia, have made certain Improvements in Lath- Machine's; and I do hereby declare that the following is a full and eXact description of the same, reference being had to the accompanying dra-Wings and to the letters and figures of reference marked thereon, similar letters and figures referring to corresponding parts of the machine.

The nature of my improvement consists in providing` the machine With a gage Which is furnished with a vibratory motion-and answers the double purpose of regulating the thickness of the lath-andslipping itl from the knife and table in order to be sure of its separation from the board so as it can be shoved up at every stroke of the machine-and thereby cut a lath.

To enable others skilled in the art to make and use my invention I Will proceed to describe its construction and operation by reference to the accompanying drawings.

Figure' l, represents a front elevation of the machine with all its parts attached. Fig. 2, represents a transverse sectional elevation through the center of the machine. Fig. 3, is a top view of the same. Fig. 4, represents a rear elevation showing how the knife frame is connected with the knife, &c.

(a a) represents the foundation timbers of the machine; (b b) the upright timbers, one at each corner, furnished with connecting timbers (c c) at the top.

(e) is the driving pulley of the machine placed on the shaft (10) which is furnished With a balance Wheel (ll) and crank (l2) which Works the pitman (f) by which the lever (g) receives its motion-that Works the beam (el) and knife frame (/zy lz.) are the connecting links between the beam and knife frame, each end being provided With bearing (7, 7) on the beam and frame.

y' j represents the knife in four different pieces. The objects of having the knife cut in this Way is to make them more easily forged and tempered than to have them all in one piece, and should any one of them become dull, or anyvvise injured it Will be handier to make the necessary repair by having them cut in section as represented than if the knife was all in one piece.

(6, 6) are guide pieces screwed to the table (la) in order to prevent the knife Afrom springing onto the table during the operation of the machine.

(m) is a connecting link for Working the lever (a) and gage piece (o), the gage piece (o) being used for governing the thickness of the lath, ivhich'is placed directly behind the top edge of the table (7s), on which the piece of timber is placed for cutting the lath. The gage (o) has a reciprocal motion, Which is given to it through the lever (g) to Which the connecting rod (m)` is attached at (9)-and through its connection gets its motion. This motion is used for the purpose of forcing the lath down from the table after it is separated from the timber. B v the front edge of the gage (0) resting against it in its downward motion, the gage going doivn Wh ile the knife is ascending-and Without such an arrangement the lath would have a tendency to stick, and thereby choke the machine.

g) represent the guide grooves for the knife frame (2'), (see in Figs. l, and 4,) and Fig. 5, represents a sectional rim of the guide pin (6) which is placed before the knife on each side, to prevent it from catching in the table.

(8 8) are the bearings in which the beam (d) Works.

What I claim and desire to secure by Letters Patent is- Imparting a vibratory motion to the gage bar (o) in the manner described so that it will not only perform the function of a gage bar to regulate the thickness of the lathbut also that of a ipper-in order to insure the separating of the lath from the block, for the purposes described.

I. R. SHANK.
